Subsequent runs have, however passed. Has anyone else hit this on
trunk?
I am running using "ant clean test"
I'm on a Mac Pro 4 core, 4GB machine, if that helps at all. Not sure
how to reproduce at this point, but strikes me as a threading issue.
Oh joy!
I'll try to investigate more tomorrow to see if I can dream up a test
case.
